Cleaning NL (fiberglass) shell

I have a 2007 NL that currently lives outside uncovered. I'm hoping to get that resolved this year, but in the mean time I'm curious about proper cleaning others have performed. I wash it less than it should be really, but need some guidance on lichen and streaks. The sides get sprayed when they start looking green but I dont get up top often.

I have a soft brush on a pole and a microfiber covered sponge thingy. I usually use auto soap with "wax" in it and go to it. In areas that are bad, I have stiffer brushes and used dawn this time. Cleaned the sides ok, but the top is fighting back a bit. And what do you recommend for streaks (water drain path down from battery door for example)?

Camper place recommended 303 Aerospace Cleaner but reviews suggest that it leaves silicon. If I was properly wont silicon be a problem?
  • Until you clean the roof don't bother cleaning anything else. The roof will continue dripping crud onto the trailer sides.
  • I have checked zep's web site but dont see one that appears to match what you've described. Could you post a product link or number to get an idea of what you're recommending?
  • I have posted my results and recommendations several times recently but the response seems minimal. I will try once more. I put ZEP acrylic finish on my 2005 camper about 5 years ago. The results are still amazing. My camper had sat over a year under trees. The roof was covered with muck and green scum in addition to twigs and leaves. I cleared the roof then I rinsed off the camper. I did not even need to wash it. There were no streaks, no dirt or stains. The finish still looked great and water still beads on the surface.

    Seriously?
